           Summary: Playback sometimes start without sound
    Classification: Platform
           Product: GStreamer
           Version: 0.10.34
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: don't know
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: tvrtko.ursulin at onelan.co.uk
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


Playing a MPEG transport stream from disk with a simplest gst-launch invocation
like gst-launch-0.10 playbin2=file://... and playback starts without sound in a
certain percentage of invocations.

Test stream (~35Mb) available on request.

If sync=false on the output alsasink then sound always work but with a sync
issue.

May be a core issue and not specific to MPEG TS since I am seeing similar
problem when playing V4L2 video with ALSA sound.
